What is the function of engine oil additive?

[VonLouis]

Engine oil additive can protect the engine. The related introduction of engine oil additive is as follows: Functions of engine oil additive: Engine oil additive can protect the engine, significantly reduce wear, prevent engine overheating, and extend engine life; enhance the comprehensive performance of lubricating oil, with significant improvements for both synthetic and mineral oils. Functions of engine oil: Lubrication to reduce wear. There is rapid relative sliding between the piston and cylinder of the engine, as well as between the main shaft and bearing bush, which can easily cause wear. High-quality engine oil can form a sufficiently thick oil film between the two sliding surfaces, separating the surfaces of the relatively sliding parts, thereby achieving the purpose of reducing wear.

As someone who frequently deals with car repairs, I believe the biggest benefit of oil additives is their ability to clean carbon deposits and impurities inside the engine, reduce friction and wear between parts, and extend the oil's service life, helping to save some money on oil changes. However, it's important to note that using the wrong type or incompatible oil can lead to corrosion or clogging. I've seen many cars develop issues after using inferior additives. It's best to check your car's manual, choose reputable brands, and add them regularly to keep the engine running smoothly. They're particularly effective for older cars, helping to alleviate oil burning problems.

As a car enthusiast who frequently modifies vehicles, I have deep experience with oil additives. They enhance the lubricity and cleaning ability of the oil, significantly reduce engine noise, and improve power response, making acceleration feel smoother—like giving the engine a deep treatment. Long-term use can also prevent carbon deposits and sludge formation, avoiding cylinder scoring and other issues. However, don't expect it to replace good-quality oil; it should be combined with regular maintenance. I've tried several types, and expensive ones aren't necessarily better—the key is finding a formula that suits your car model. Over-reliance can just waste money.

I haven't been driving for long, but simply put about additives: they mainly help clean dirt inside the engine, reduce friction to protect components, and also improve lubrication to make the engine run smoother. I've used them and noticed less noise and a slight drop in fuel consumption, but experts say don't overuse them as it may backfire. Regular maintenance is sufficient, additives are just supplements.
